Ovulatory disorder is a term that describes a group of disorders in which ovulation fails to occur, or occurs on an infrequent or irregular basis. Ovulatory disorders are one of the leading causes of infertility.
There are two primary types of ovulatory disorders: anovulation and oligo-ovulation.
Indicators of ovulatory disorders
Anovulation, or no ovulation, is a disorder in which eggs do not develop properly, or are not released from the follicles of the ovaries.
